Glyceryl Monooleate, also known as monoolein, is a glycerol monoester derived from oleic acid. It is formed by the esterification of glycerol with oleic acid, resulting in a molecule consisting of a glycerol backbone and a single oleic acid molecule attached. It is used as a mulsifier, helping to blend oil and water-based substances together, and as a permeation enhancer, promoting the absorption of certain drugs through biological barriers.
